Abstract: PURPOSE: A low fired dielectric ceramic composition is provided to ensure 220 MPa or more strength value and low dielectric loss. CONSTITUTION: A brosilicate glass frit contains 60-70 mole% of SiO2, 15-30 mole% of B2O3, 1-5 mole% of Al2O3, 0.1-3 mole% of Li2O and 0.5-15 mole% of at least two or more selected from MgO, CaO, SrO, and ZnO. A low fired dielectric ceramic composition contains borodilicate glass frit; at least one or more filler selected from single and complex oxide comprising Al2O3, SiO2, cordierite, Mullite, MgAl2O4, ZnAl2O4, Mg2SiO4, and ZrSiO4; at least one or more ceramic selected from CaTiO3, SrTiO3, and BaTiO3.
